S. H. SCUDDER ON PALAEOZOIC COCKROACHES. 131 



Fig. 15. EtoblatUna anaglyptica (Germ.), p. 09. Copied from Germar's Versteinerungen des Steinkohlen- 

 gebirges von Wettin, etc., pi. 31, lig. 4 ; reversed, and the apical margin restored. The basal curve of the 

 main veins is not well represented. 



Fig. 16. EtoblatUna euglyptica (Germ.), p. 60. Copied from Germar's Versteinerungen des Steinkohlen- 

 gehirges von Wettin, etc., pi. 31, fig. 8, with the apical margin restored. Cf. pi. 4, fig. 7. 



PLATE III. 

 See preliminary explanations to Plate II. 



Fig. 1. GerablatUna weissiana (Gold.), p. 109. Copied from the Neues Jahrbuch fur Mineralogie, 1868, 

 pi. 3, fig. 10; with part of the inner border restored. The outside mark, indicating the lower limit of the 

 externomedian area is placed much too far from the tip of the wing; there should be also a single branch to 

 the internomedian vein. 



Fig. 2. GerablatUna producta Scudd., p. 106. Copied from the Neues Jahrbuch fur Mineralogie, 1868, 

 pi. 3, fig. 9 ; reversed. 



Fig. 3. GerablatUna scaberata (Gold.), p. 102. Copied from Goldenberg's Fauna savaepontana fossilis, ii, 

 pi. 1, fig 8 ; reversed. The branch of the externomedian vein, being conjectural, should have been dotted 

 throughout. 



Fig. 4. Gerablattina clathrata (Heer), p. 100. Copied from the Vierteljahrsschrift der naturforschenden 

 Gesellschaft, Zurich, ix, pi., fig. 3; with the inner and apical margin restored. This figure accidentally repre- 

 sents the wing as magnified a little less than two diameters. 



Fig. 5. EtoblatUna labacJiensis (Gold.), p. 59. Copied from Goldenberg's Fauna saraepontana fossilis, i, 

 pi. 2, fig. 15 ; reversed. 



Fig. 6. Gerablattina Germari (Gieb.), p. 107. Copied from Germar's Versteinerungen des Steinkohlenge- 

 birges von Wettin, pi. 31, fig 9. 



Fig. 7. EtoblatUna prima* va (Gold.), p. 58. Copied from Palaeontographica, iv, pi. 3, fig. 4*. 



Fig. 8. EtoblatUna mantidioides (Gold.), p. 72. Copied from the Geological Magazine, iv, pi. 17, fig. 6. 

 The restored outline of the apical half of the wing is undoubtedly incorrect, and the inner margin of the 

 base is represented as much too convex; a corrected figure will be found in the text, p. 73; the outside mark 

 indicating the lower limit of the scapular area should be removed to the apex of the wing. 



Fig. 9. EtoblatUna leptophlebica (Gold.), p. 77. Copied from the Neues Jahrbuch far Mineralogie, 1869, 

 pi. 3, fig. 1"; reversed, and with the apical margin restored. 



Fig. 10. Progonoblattina helvetica (Heer), p. 119. Copied from the Vierteljahrsschrift der naturforschen- 

 den Gesellschaft, Zurich, ix, pi., fig. 1. 



Fig. 11. GerablatUna intermedia (Gold.), p. 101. Copied from Goldenberg's Fauna saraepontana fossi- 

 lis, ii, pi. 1, fig. 10 ; reversed. 



Fig. 12. Progonoblattina Fritschii (Heer), p. 120. Copied from the Vierteljahrsschrift der naturforschen- 

 den Gesellsi halt, Zurich, ix, pi., fig. 2; with the apical margin restored. 



Fig. 1:;. '.' rablattina Goldenbergi (Mahr), p. 98. Copied from the Neues Jahrbuch fur Mineralogie, 1870, 

 p. 284, fig, 1 ; with the apical margin restored. 



Fig. 14. Gerablattina Mahri (Gold.), p. bis. Copied from the Neues Jahrbuch far Mineralogie, 1870, 

 p. 284, fig. 2"; with the basal and apical margins restored. 



PLATE IV. 

 See preliminary explanations to Plate II. 



Fig. 1. Anthracoblattina RiXckerti (Gold.), p. 96. Copied from the Neues Jahrbuch fur Mineralogie, 1S6S, 

 pi. 3, fig. 11 ; with most of the border restored; probably this represents tie 1 wing as broader than it should be. 



Fig. 2. Anthracoblattina Remigii (Dohrn), p. 95. Copied from Palaeontographica, xvj, pi. 8, fig. 3, 

 with the inner and apical margins restored. 



Fig. 3. Slattina latinervis Heer, p. 127. Copie 1 from the Vierteljahrssehrifl der naturforschenden Gesell- 

 schaft, Zurich, ix. pi , fig 4 1 .
